美工妹子给的图如下,订单在创建时间的24小时后进行关闭
业务逻辑
从后台返回来的订单创建时间加24小时后减去你当下的时间
就是相差的总共时间,然后进行倒计时
倒计时结束后上传订单关闭标识,改变状态页
实现思路
可能在没有遇到CountDownTimer之前,我们都是创建Handle来开启异步线程来处理,如果你现在使用,我只能说太菜了,官方已经为我们封装好了一个类,爽的很,一起来看
@Override
public void initData() {
countDownTimer = new CountDownTimer(time, 1000) {
@Override
public void onTick(long millisUntilFinished) {
if (!TestActivity.this.isFinishing()) {
long day = millisUntilFinished / (1000 * 24 * 60 * 60); //单位天
long hour = (millisUntilFinished - day * (1000 * 24 * 60 * 60)) / (1000 * 60 * 60);
//单位时
long minute = (millisUntilFinished - day * (1000 * 24 * 60 * 60) - hour * (1000 * 60 * 60)) / (1000 * 60);
//单位分
long second = (millisUntilFinished - day * (1000 * 24 * 60 * 60) - hour * (1000 * 60 * 60) - minute * (1000 * 60)) / 1000;
//单位秒
textView.setText(hour + "小时" + minute + "分钟" + second + "秒");
}
}
/**
*倒计时结束后调用的
*/
@Override
public void onFinish() {
}
};
countDownTimer.start();
}
传了两个参数,第一个参数就是时间的总值,换算成毫秒值,第二个代表以毫秒来计算
两个方法:
onTick :倒计时执行的方法
onFinsh:倒计时结束后的方法
countDownTimer.start(); 开始倒计时
就是这么简单,但是两个坑,来看下
-
空指针问题
在某些场景下，CountDownTimer 会导致空指针 如果在Activity或者Fragment被回收时并未调用CountDownTimer的cancel()方法结束自己，这个时候CountDownTimer的Handler方法中如果判断到当前的时间未走完，那么会继续调用onTick方法，Activity或者Fragment已经被系统回收，从而里面的变量被设置为Null，同时，CountDownTimer中的Handler方法还在继续执行，这一块空间始终无法被系统回收也就造成了内存泄漏。
*在CountDownTimer的onTick方法中记得对当前对象做判空处理
*#####可能造成内存泄漏问题
* 记得关闭,负责内存溢出
*/
@Override
protected void onDestroy() {
super.onDestroy();
if (countDownTimer != null) {
countDownTimer.cancel();
countDownTimer = null;
}
}
